In the mounting of telescope sights upon firearms it is of course obvious that Fig. 3 is a perspective view of the hold-down band.

Fig. 4 is an end view similar to Fig. 2 with a slightly modified form of the invention wherein the sights must be frequently connected and disthe mounting fits closely upon the barrel of the 5 connected as the gun is used or transported. firearm. It is desirable, therefore, to have a mounting Fig. 5 is a side elevation of the barrel of the for the telescopic sight which will accurately rm and telesc pe wh rei the mounting is and positively locate the sight in proper aligned e up of two sep ly spaced brackets which position with respect to the barrel of the firearm. e d the te es p in position- 10 Various types of telescope mountings for fire- 6 s a Se on ta en On the e 6-6 o arms have been provided heretofore but it is 5- believed that the present mounting is of advan- In Fig. 2 the barrel or action of the firearm is tage over those previously provided because of indicated nerally at 2 and the telescope is the fact that various diameter telescopes may shown at 3.

These arms serve to 1s a peljspectlve one form of the support the telescope and each arm is provided mounting and illustrates a single bas bracket with the inclined faces l5 and I6. These faces 50 which can be attached the firearm P- are inclined downwardly and inwardly toward ng t e telescope. each other so that they meet at a theoretical g. 2 is an end view of the bracket shown in or actual apex I! to form a substantial V. Par- Fig. 1 and illustrating a part of the firearm and ticular attention is directed to the fact that 5 the telescope in section. these seats are flat because t is intended that the telescope will contact these seats at a single point, or rather, along a straight line. As seen in Fig. 2, the contact line is shown at 20 and 2!, where the curved periphery 22 of the telescope contacts the fiat faces of the seat.

This particular form of fiat seat has been provided so as to accommodate telescopes of different diameter, because regardless of a change in diameter the contact line will be somewhere along the flat faces I and Hi. There will be no accurate fitting of the telescopes to the mounting required, as is now necessary where the telescope mounting is provided with a curve or semicircular seat. Another advantage of having the flat faces I5 and I6 is that thetelescope will always seat in its proper position by aligning itself when it is fixed into position due to the V-shaped seat. It is to be understood that the arms l2 and I3 may be of any desired width in order to form a suitable base or seat forthe telescope.

In Fig. 4 a slightly modified form of the mounting has been shown wherein the inside contour of the bracket has been formed with a face 25 which substantially fits the contour 6 of the gun barrel or action, regardless of the shape thereof. This may be desired in some instances and insures proper alignment of the bracket or mounting with respect to the gun. The other parts of this bracket, including the attaching means and the telescope seat, are substantially the same as described in connection with Fig. 1.

In some instances where the telescope is to be attached to the firearm separate bracket mountings may be desired as seen in Fig. 5 where the bracket 4 has. been made in two parts such as 26 and 21. These two parts may be attached to the barrel or to the action part of the firearm separately by means of the screws 28, as seen in f Fig. 6. The seating arrangement for the telescope in this form is the same as seen in Fig. 1.

With all three forms of the brackets which have been described it is intended that the telescope will be held in position by means of one or more hold-down bands 30, one of which is best seen in perspective view in Fig. 3. This band is provided with a T-head 3| by virtue of the indentations 32 which create the ears 33 to form the T. This T has been formed in order to attach one end of the band to the mounting by passing the neck portion 34 thereof into the recess 35 in the end of the arm such as [2. The underside of each arm is provided with a groove or recess 36 and into which the ears 33 will fit. It seems clear that if this T head is moved into position it can be raised slightly to assume the position seen in Figs. 2, 4 and 6 where it is aflixed against upward movement. The main portion of the band is then passed over the telescope 3 and the hold-down screw 38 is then screwed into the threaded recess 36 in the bracket. In this manner the band can be drawn down tightly over the telescope, but particular attention is directed to the formation of the hold-down lip 31, of the band which is best seen in Fig. 2, it being intended that the band will be of a length such that the lip will not seat on the arm of the bracket when the telescope is firmly clamped. In this manner the various sizes of telescope can be accommodated and the telescopes will be positively held in position due to the tension applied to this band before it has been seated upon the bracket. In Figs. 4 andv 6 the angular face 40 is of such an inclination that the end of the band 4|, which is held down by the hold-down screw, is not in alignment with such face so that additional tension can always be placed upon the band by additional tightening of the holddo-wn screw.

From the foregoing it will be obvious that the invention broadly contemplates a bevel of the V-type of seat for a telescope mounting in which the telescope can be held in position by quickly releasable bands which will accommodate telescopes of various sizes.

It is to be understood, however, that other than a flat face or V-type seat may be provided so long as a double line contact is maintained between the telescope and the mounting.

What is claimed is:

In a telescope mounting a bracket being shaped to form a flat V-shaped seat thereon, a telescope resting on said seat, there being a groove at one side of the seat, said bracket being shaped to form a face at the opposite side of the seat angularly related to the faces of the V-shaped seats, a resilient band, a head on one end thereof adapted to be engaged within said groove, and means for securing the opposite end of the band to said angular face to move the end toward the plane of the face so that tension may be placed upon the band to hold the telescope in position upon the seat.
